UNTE STATES PA i GEORGE RUSSELL WYAT'I, OF REDWOOD CITY, CALIFORNIA, ASSIGNOR OF THREE- EIG-HTI-IS TO ALBERT MILES TAYLOR AND ONE-FOURTII TO THOMAS D. EVANS, OF

REDWOOD CITY, CALIFORNIA.

To all whom tt may concern:

Be it known that I, Grenen RUSSELL llzfriirr, citizen of the United States, residing at Redwood City, in the county of San Mateo and State of California, have invented new and useful Improvements in Oil- Burners, of which the following is a specilication.

My invention relates to oil burners and pertains especially to a burner and generator for use in cook stoves and the like.

The invention consists ofthe parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which-- Figure 1 is a longitudinal section of the invention. Fig. 2 1s a plan view of the burner as appliedn Fig. 3 is a cross-section on the line X-X, Fig. 1. Fig. d is a section on the line iT-Y, Fig. 1.

rihe burner proper comprises a double ended'tubular casing A, having symmetrical ends, and the ends closed by the caps 2, eX- cept for the small openings 3, through which the inflammable gas generated in the gen-- erator 4imay escape into the lire box 5 and there be ignited.

Inside the burner casing is a combined double ended valve and tip cleaner 6, which is reciprocal in the casing to move into or out of one or the other of the orifices 3, according to the direction in which the member G is reciprocated. The ends of member 6 are pointed, as shown, so as to fit the corresponding flared or concaved inner ends of the orilices 3.

The reciprocation of the member G to open or close, or to clean one or the other of the eriices is done by appropriate means, as by a handle 7, supported in a tube S, which latter screws into one side of the casing A. The inner end of the handle has a crank arm projection 9 to tit hole 10 in the member G. On the other end of the handle 7 is a hand-wheel 11 by which the handle can be rocked to move the member G back and forth.

rThe generator 1l, which extends parallel with the casing A has a suitable discharge into the burner between the ends of the latter. The other end of the generator extends outside of the fire box and connects with the oil supply pipe 12, through which the oil is fed either by gravity or pumped under suitable pressure.

OIL-BURNER.

Patented Oct. 5, 1909. Serial No. 490,097.

rThe generator incloses a snug litting plug 13, which has a nut portion lll, screwing into a T l5, into which the generator et and oil pine 12 also screw. T he top of the plug 13 when screwed into position has a longitudinal groove or trough 1G, through which the oil flows toward the burner; the T l5 inclosing a suitable annular space through which the oil may pass around the plug 13 and iiow thence through the generator confined in the comparatively narrow groove 16.

The object of plug 13, with the trough portion 1G, is to reduce the size of the oil passage in the generator so that no considerable quant-ity of oil will collect therein with the consequent danger of being rapidly converted into gas and causing a back pressure in the oil pipes and possibly result in explosion. Also, and what is more important, this trough with its large body of metal, represented by the plug 13 and which is cooler than the top of the generator tube a nearer the iame, will operate to collect the asphaltum and other heavy non-volatilizing matters, the more volatile portions of the cil being rapidly converted into gas and passing thence out through the orifices 3 of the burner. `Without the use of the groove and plug 13, or some equivalent means for collecting the asphaltum and like heavier residue, there is more or less tendency t0 soot, which is avoided to a great extent by my burner.

lVhen the burner is installed in the tire box represented at 5, it is placed about centrally thereof and so disposed that a jet or flame may be directed from each end of the burner in opposite directions against an asbestos or other lire-proof wall or surface 17 at the ends of the lire box. The purpose of these asbestos, or like lire-proof walls, is

to arrest and spread the volume of the discharged vapor and elfect a complete con1- bastion of the same.

Since the orifices 3 are con'iparatively small they have more or less tendency to clog, but by a small turn of the handle 7 the member 6 is shift-ed in one direction or the other to drive the sharp point of the member into the orifice and remove any obstruction.

Since one end of the burner is directed over and in line with the generator the latter is maintained het by the flame and consequently a suitable quantity of gas is generated for a continual supply to the burner. It only a small flame is needed, such as can be supplied by one or the ot-her of the jets at either end et the burner, the handle 7 is turned to shift the member 6 and close one or the other of the orifices 3 whereby only half the amount of gas will be consumed. If a large lire is needed the member 6 is turned in a cent-ral position and leaves both orices 3 open.

Having thus described myinvention, what lf claim and desire to secure by Letters Patent isl. An oil burner coinprising a double ended casing each end of the casing having a gas o-utlet and a member having a needle point at each end reciprocal between said gas outlets, and operative alternately .to close one outlet and open the other, or vice versa, and means for reciprocating said member.

2. An oil burner comprising a double ended casing each end et' the casing having a gas outlet and a member having a needle point at each end reciprocal between said gas outlets, and operative alternately to close one outlet and open the other, or vice versa, and means for reciprocating` said member, said last named means comprising a handle having a crank arm projection engaging centrally of said member and a tubular guide connected with the casing through which said handle passes.

3. An oil burner consisting of a double ended casing with a central perforated tip for each end of the casing, a needle pointed memberl in the casing and operative to close one tip when moved in one direction and correspondingly open the other tip, and vice versa, means for reciprocating said member, and a generator tube entering the casing between its ends, said generator tube extending parallel with the burner casing.

4. n an oil burner, the combination with a double-ended casing having gas outlets, and means controlling said outlets, of a generator tube entering the casing between its ends and said generator tube extending parallel with the burner casing, and a solid plug in the generator tube substantially filling the generator tube, except for a longitudinal groove at the top ot1 the plug, and means tor feeding oil in said groove.

5. rlhe combination with a lire box of a double ended burner casing within the ire box, said double ended burner casinghaving perfo ated end tips, a member reciprocating within the casing and having pointed ends to fit the pertorations in said tips, means ter reciprocating said member from a point eXterior to the tire bex, and a generator arranged parallel with the burner casing and connecting therewith between its ends, said generator extending exterior to the tire box and connected with the oil supply pipe.

ln testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
